Answer 3

You have seen the answer, but do you know how to get it ?
Use the FOIL method. FOIL stands for first,outside,inside,last.

(2x - 9)(x + 6)

First -- multiply 1st terms in each set....2x * x = 2x^2
Outside -- multiply outside terms in each set...2x * 6 = 12x
Inside -- multiply inside terms in each set...-9 * x = -9x
Last -- multiply last terms in each set...-9 * 6 = -54
Now put it all together..
2x^2 + 12x - 9x - 54 --- combine like terms
2x^2 + 3x - 54

There you go...just in case you were wondering how to get the answer :)
